AI's Hidden Footprint: The Environmental Cost of Technological Progress

The rise of technological advancements has brought about both excitement and concern for the future. On one hand, technologists see great potential in artificial intelligence, robots, and cryptocurrencies to transform our world. However, on the other hand, environmentalists such as Sir David Attenborough and movements like Extinction Rebellion warn that we risk trashing the only planet we have.

The illusion of a 'weightless' digital world is shattered when considering the physical infrastructure required for its maintenance. Bitcoin's proof-of-work mechanism, for instance, requires vast amounts of computing power, which consumes energy. Similarly, artificial intelligence relies on data centres filled with GPUs, storage, and cooling systems, all of which demand electricity.

The numbers are striking: in 2024, data centres consumed around 415 terawatt-hours of electricity, equivalent to 1.5% of global electricity consumption. By 2030, this figure is expected to more than double to around 945 TWh, with AI being the primary driver of growth.

The IEA highlights that while AI can optimize energy systems and improve efficiency, demand for computation is growing faster than efficiency gains. This raises concerns about the environmental impact of our technological progress. Attenborough emphasizes that we must consider the natural systems upon which human civilization depends, suggesting that we need to rethink what we're optimizing for.
